Pinpoint Test

1. Using a scan tool, perform the PCM KOEO self-test.

Are any DTCs recorded? 

1. Yes: REFER to SECTION 3: SYMPTOM CHARTS .
2. No: GO to 2  .

1. Using a scan tool, perform the IPC self-test.

Are any DTCs recorded? 

1. Yes: For DTC U0100:00, REFER to Diagnostic Routine AR: U0100:00 .

   For all other DTCs  , REFER to DTC Chart: Instrument Panel Cluster (IPC) .

2. No: GO to 3  .

1. Ignition ON.
2. Using a scan tool, view the IPC PIDs  .
3. Select the IPC tachometer (TACH_IND) PID. Command the tachometer in 10% increments while monitoring the tachometer.

Does the tachometer indication increase by 600 RPM (optional IPC bar graph display), 700 RPM (base IPC or IPC analog gauge display) for each 10% increment? 

1. Yes: GO to 4  .
2. No: INSTALL a new IPC. REFER to Instrument Panel Cluster (IPC) .

1. Using a scan tool, view the PCM PIDs  .
2. Select the PCM engine RPM PID (RPM) and set the engine RPM to 1, 000, 1, 500, 2, 000 and 2, 500 RPM.
3. Monitor the engine PCM RPM PID (RPM) with the engine at 1, 000, 1, 500, 2, 000 and 2, 500 RPM.

Does the tachometer indication range between 944-1, 056 at 1, 000 RPM, 1, 444-1, 556 RPM at 1, 500 RPM, 1, 944-2, 056 RPM at 2, 000 RPM and 2, 444-2, 556 RPM at 2, 500 RPM? 

1. Yes: The tachometer is operating correctly at this time.
2. No: INSTALL a new IPC. REFER to Instrument Panel Cluster (IPC) .
